coaPoRATIoN OF Application led April 4. 1924. Serial No. 704,139.

Bc it known that l. 'IHnononn A. Jos'rnn'r, a citizen of the UnitedStates, and residing at St. Louis. State of Missouri, have invented thenew and useful'llnprovement in Hinges, ot which the following is aspecification. v

This invention relates to hinges, and more particularly to door hingessuch as may be used for instance on refrigerator doorsl and the like.

One of the objects of thisv invention is to provide a hinge which, whileperforming all the functions of an ordinary hinge, will also act asa'stop to limit the movement of the door so as to position the same whenopen.

Another object is to provide such a hinge which will be capable oflimiting the movement ofthe door in bot-h directions.

Further objects will appear from the detail description taken inconnection with the accompanying drawing, in which:

Figure 1 represents a top View of a hinge embodying this invention andshowing its application to a refrigerator door;

Figure 2 is afront view of the hinge; and

Figure 3 is a fragmentary view 1n perspective showing more clearly theconnection of the stop to the-hinge butt.

Referring to the accompanying drawing, thehinge illustrated comprises abutt 1 and a strap 2 joined at the knuckle 3 by a hingepin 4. Theseparts may be of any ordinary well known constructlon such as is welunderstood in the art.

The butt 1 is provided with a pair of upstanding ears 5 spaced oneopposite the other in a vertical direction and provided with verticallyalined perforations 6. The ears 5 may be placed at the end of the butt 1opposite the knuckle 3 so as to be spaced from said knuckle. The. ears 5also are rovided with notches 7 for a purpose w ich will be explainedpresently. ,The strap 2 is provided with an extended shank 8 u on whichis mounted a -rib or rail 9 up-standlng from the shank so as to rovide aslot 10, between the rail and the s ank, the slot extending along theshank... A U shaped link 11 has its closed end engaged under the rail 9so as to'be slidable in and along the slot 10. At the open end of theU-shaped link the le 12 thereof are provided with voutturne ends 13adapted for insertion into the perforations 6 so as to provide a pivotalconnection between the link 11 and the butt 1. The. legs 12 are.normall)1 spaced from one another a distance somewhat greater than thatbetween thc ears 5 s-o that in order to engage the ends 13 in thepcrforations the legs must he sprung together. lVhen thus sprung intothe ears 5, the ends ot the legs 12 tit into the notches 7 and arepressed into said notches with a yielding pressure due to thc resilienceof the legs. Thus a yielding pivotal connection is provided between thelink 11 and the butt 1. At the same time a variable or slidingconnection is provided between the closed end of the link and the strap2 by means of the rail 9.

The hinge may be applied as illustrated in Figure 1. The butt 1 is fixedto the door frame 14 and the strap 2 to the door 15. lVhen the door isopened the hinge may be swung to the position shown in dotted lines inFigure 1. ln moving to this position from the closed position the link11 slides in the slot 10 until the end of the link comes into engagementwith the end of the slot, after which no further movement of the door ispossible. The link 11 thus provides a stop adapted to limit the swingofthe door inthat direction. When the hinge is in this position, theends of the legs 12 are pressed' into the notches 7 as illustratedy inFigure 3. As the door is swung from the position shown in dotted linesin Figure 1 in a direction to .close the same, the link or stop 11 willpivot in the ears 5 until the legs 12 come into engagement with theinner shoulders 16 of the notches 7 These shoulders will then restrainfurther movement of the door in the closing direction. The shoulders 16are,'howe ver, inclined so as to provide in effect cam surfaces whichwhen 'the closing pressure on the door is increased, will cause the legs12 to be sprung together so as to rise on the cams 16 to the positionindicated in Figure 2, and allow further movemnt'of the door to `closedposition.

It will be seen, therefore, that in accord- !ance with this invention ahinge is provided which when the door is opened will keep the same open,limiting its movement in two directions, so that it will be preventedeither from opening too far so as to strike an adjacent wall forinstance, or from closing prematurely. The butt of the door is connedbetween two definitely established limiting positions, one as shown indotted lines in Figure l in which the stop 11 has moved to the end ofthe slot 10, and the other as indicated in Figure 3 Where the legs 12will come into engagement with the shoulders 16. The sprung or yieldingApivotal mounting of the stop 11 in the ears 5 provides that the doormay be closed from this latter position by Simply increasing the closingeffort so as to overcome the resilience of the stop 11.

It is obvious that various changes may be made in details ofconstruction Without departing from the spirit of this invention; it is,therefore, to be understood that this invention is not to be limited tothe specific details shown and described.

Having lthus described the what is claimed is:

l. A door hinge, comprising, a butt, a strap connected thereto by ahinge pin, and a stop yieldingly pivoted to said butt and connectingsaid butt and said strap adapted to limit the movement oi" the door` intwo directions. Y

2. A door hinge, comprising, a butt, a strap connected thereto by ahinge pin, and a stop having a yielding pivoted connection with one ofsaid members and connected to the other member, adapted to yieldinglylimit the closing movement of the door.

3. A door hinge, comprising, a butt, a strap connected thereto by ahinge pin, and a stop having a yielding pivoted connection with one ofsaid members and connected to invention,

Leemans the other member, adapted to limit theopening movement and toyieldingly limit y the closing-movement of the door.

.with one of said members and connected to the other member, adaptedclosing movement of the door. l

5. A door hinge, comprising, `a butt, a strap connected thereto by ahinge pin, and a stop having a sprung pivotal connection with one ofsaid members and a sliding connection with the other member, adapted tolimit the closing movement of the door.

6. A door hinge, comprising. a butt, a strap connected thereto by ahinge pin, a stop having a sprung pivotal connection with one of saidmembers and a sliding connection with the other member, and a camcooperating with said pivotal connection to lylfieldingly limit theclosing movement of the r oor.

7. A. door hinge, comprising, a butt, a strap connected thereto by ahinge pin, and a stop having a Sprung pivotal connection with Ione ofsaid members and a sliding connection with the other member, said butthaving a notch adapted to receive said stop in sprung engagement tolimit the closing movement of the door.

In testimony whereof I affix my signature this 18th day of March, 1924.
